Plant Pot Riser

Plant Pot Riser Large (27,5 cm wide x 20 cm high) (approx. 10.8 inch wide x 7.9 inch high)

you can scale this but do not make it to small otherwise it cannot handle the weight.
i printed this with a 20% infill, if you are going to use heavier pots or plants you can increase this to strengthen the print.

this comes with wife approval and saves a lot of money, the steel variant costs 50 euro in the store.
